[Satellites (Satetsu)] I Was Allured by a Little Demon and We Had Semen-Draining Sex [Panatical]

Maho-chan is a little demon with a spade-tipped tail and bat wings who wants exactly one thing: onii-san's semen, and she shows up right after school to drain him of every drop. Still wrapped in her school jacket, she worships him with her mouth before offering her tiny body, riding him until he presses his hips flush against her and cums a huge amount deep inside her tight pussy. What follows is an afternoon-long marathon across his bed, desk, and floor, the honor student happily skipping class as she takes him in every position, begging for him to slam deeper and fill her over and over until they're both completely spent.
